Display apparatus, display method, and program

Abstract

There is provided a display apparatus including an observation position detection unit for detecting an observation position of an observer, a generation phase determination portion for determining a generation phase for each viewpoint of a multi-viewpoint image for a plurality of viewpoints depending on the detected observation position, a multi-viewpoint image generation unit for generating a viewpoint image for each viewpoint from a predetermined image depending on the determined generation phase, a display device configured to include a display area having a plurality of pixels arranged thereon, for displaying the viewpoint image for each viewpoint such that the viewpoint image can be observed in each of a plurality of observation areas, and a light beam controller configured to be disposed in front of or behind the display device, for restricting a direction of light beams emitted from the display device or incident on the display device.

The invention is claimed as follows: 
     
         1 . A display apparatus comprising:
 an observation position detection unit for detecting an observation position of an observer;   a generation phase determination portion for determining a generation phase for each viewpoint of a multi-viewpoint image for a plurality of viewpoints depending on the detected observation position;   a multi-viewpoint image generation unit for generating a viewpoint image for each viewpoint from a predetermined image depending on the determined generation phase;   a display device configured to include a display area having a plurality of pixels arranged thereon, for displaying the viewpoint image for each viewpoint such that the viewpoint image can be observed in each of a plurality of observation areas; and   a light beam controller configured to be disposed in front of or behind the display device, for restricting a direction of light beams emitted from the display device or incident on the display device.   
     
     
         2 . The display apparatus according to  claim 1 , wherein the generation phase determination portion determines the generation phase by calculating a correction amount corresponding to an amount of the observation position deviated from a reference position and by adding the correction amount to a predetermined generation phase for each viewpoint. 
     
     
         3 . The display apparatus according to  claim 1 , further comprising:
 a storage unit for storing an offset value based on an amount of a disposition position of the light beam controller deviated from a desired position relative to the display device,   wherein the generation phase determination portion determines the generation phase on the basis of the stored offset value.   
     
     
         4 . The display apparatus according to  claim 1 , further comprising:
 an image acquisition unit for acquiring a first original image and a second original image,   wherein the multi-viewpoint image generation unit generates the viewpoint image for each viewpoint from the first original image and the second original image depending on the determined generation phase.   
     
     
         5 . The display apparatus according to  claim 1 , wherein the observation position detection unit detects a position of a head, face or eye region from a face image obtained by capturing the observer. 
     
     
         6 . The display apparatus according to  claim 1 , wherein the light beam controller is a slit array or a lens array. 
     
     
         7 . A display method performed by a display apparatus, the display method comprising:
 detecting an observation position of an observer;   determining a generation phase for each viewpoint of a multi-viewpoint image for a plurality of viewpoints depending on the detected observation position;   generating a viewpoint image for each viewpoint from a predetermined image depending on the determined generation phase; and   displaying the generated viewpoint image for each viewpoint on a display device, the display device being configured to include a display area having a plurality of pixels arranged thereon and to enable the viewpoint image for each viewpoint to be observed in each of a plurality of observation areas.   
     
     
         8 . A program causing a computer to function as:
 an observation position detection unit for detecting an observation position of an observer;   a generation phase determination portion for determining a generation phase for each viewpoint of a multi-viewpoint image for a plurality of viewpoints depending on the detected observation position;   a multi-viewpoint image generation unit for generating a viewpoint image for each viewpoint from a predetermined image depending on the determined generation phase; and   a display control unit for displaying the generated viewpoint image for each viewpoint on a display device, the display device being configured to include a display area having a plurality of pixels arranged thereon and to enable the viewpoint image for each viewpoint to be observed in each of a plurality of observation areas.
